St Denys - Southampton Central fast line issue?

[OrangeJuice]

Recently noticed over the last few days cross country trains running slow saline from St Denys to Northam Junction rather than continuing on the fast line through the level crossing with quite a slow turnout after St Denys station.
I looked on open train times this morning and it seems all fast line trains are being rerouted but nothing marked out of use on the map. Does anyone know what might be causing this?

Due to a problem with line side equipment between St Denys and Southampton Central trains have to run at reduced speed on the line towards Southampton.
What's Going On:
Train services running through these stations may be delayed. Disruption is expected until the end of the day on 17/06/24.
What We're Doing About It:
We have been informed of a problem with line-side equipment between St Denys and Southampton Central. This means that trains are running at a reduced speed on the line towards Southampton.
Services are currently required to come to a stand just outside of Southampton Central station so that the signaller can advise train drivers of an issue with line-side equipment.
For further information or onward travel advice please speak to a member of staff or use a station help point.
We are very sorry for any delay that this may cause to your journey.

That’s an unrelated issue.

Curious that National Rail don't mention any issues in the area

That surprised me too, hence my question here. I'm guessing maybe because any delays are quite small as they can run on the slow it's not being mentioned

I did wonder this the other day (Wednesday), as my cross country service slowed down to a crawl through St Denys, into and through the down slow loop without stopping then back onto the fast lines again.

Happened last Saturday (10.35 ex WAT, already 85 late owing to an incident). RTT suggests a delay of 1.5min, which in the grand scheme of things isn't significant
